Chemical Structure
Description
2,5-Dimethyl-1-pyrrolidineethanamine (CAS 33304-27-7), molecular formula C8H18N2 and molecular weight 142.24 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an organic framework, 2,5-Dimethyl-1-pyrrolidineethanamine is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
